There's a lot we still don't know about what happened in Boston last week. But new details that surfaced on Wednesday night reveal some key details that stand to change the timeline of the final 24 hours of the manhunt dramatically. Among other revelations, police are now saying that they don't believe Dzhokhar Tsarnaev, the younger of the two brothers suspected of carrying out the attack, was armed when they opened fire on him Friday evening. In fact, authorities admit that the two brothers didn't quite have the small arsenal of weapons they thought they did — just one gun, a gun that wasn't anywhere near Dzhokhar when he was found in the boat after a shootout.
Much of the new information revealed by authorities is revealed in an ambitious and valuable New York Times story that appears on the front page of the paper Thursday morning, a story that took no less than ten people to put together. In a dependable narrative fashion, the Grey Lady guides us through the instantly chaotic and still confusing events of last Thursday evening, starting with the cold-blooded killing of MIT police officer Sean A. Collier, who was mourned in Cambridge this Wednesday. Law enforcement believes that the Tsarnaev brothers tried and failed to steal Collier's gun after shooting him from behind, the first of several things that went wrong for the two young suspected terrorists that night.
